In this video instruction Kent will walk you through the steps of how to successfully replace a leaking valve cover gasket on an M104 straight 6 gas engine. Special emphasis will be placed on proper preparation and cleaning, thread inspection and proper torquing sequence.
For these old 6 cylinder gas engines of the late 80's and early 90's Kent feels this part along with the injector o-ring seals could be one of the most overlooked maintenance items on these engines.

We have been looking for a long time to find a super strong and well made tool to adjust those tough 17 mm ball adjuster sockets on the early 4 and 6 clyinder gas engines.
Oil filter changes are important, but I believe on these high interval oil change schedules that changing the oil fitler can be just as important! Use the wrong filter and the engine can suffer serious damage.
For E320, ML320, C240, C280 and C320. Every M112 V6 I have worked on starts making front engine bearing noise around 90K to 100K. Almost like clockwork! This is a service you will want to perform whether you have had your Benz for a long time or just purchased one.
Connect this small filter with attached hoses to the back of the injection pump and to the brown plastic vacuum line going to your ignition switch under the dash. The filter will do two things. 1. Help to trap oil coming out of a leaking shutoff valve before it gets to your ignition switch. 2.

Instructions to complete a diesel system purge. Does not include instructions on changing the filter
Lubro Moly Diesel hi test fuel additive that does far more than just add lubrication to the fuel. Formulated for the new low sulfur diesel fuel. Contains an additive against injection pump and injector wear.
During his years of working on diesel engines, Kent has learned a few things about glow plugs. Some he learned the easy way and others he learned by “pain and suffering.” If misunderstood or improperly maintained, glow plugs can be the “achilles heal” of a diesel.
This book explains how a parallel pre-glow system works and how to properly test it using inexpensive electrical testing equipment. If your PENCIL style glow plugs are not working properly, you need to find the cause BEFORE you start buying parts.
Book 1 explains how a series pre-glow system works and how to properly test it using inexpensive electrical testing equipment. If your glow plugs are not working you need to find the cause BEFORE you start buying parts. This is something you can do yourself.
When an engine is both overheating and losing coolant, you first want to exhaust all possibilities that the cause is something simple or inexpensive to repair. It is possible it might just be a stuck thermostat with a faulty water pump leaking coolant at the same time.
If your engine is just running hot, it may be due to a plugged radiator or possibly a stuck thermostat. If your engine is just losing coolant it could be a leak in the water pump, radiator or hoses.
In this video Kent will go through the process step-by-step of properly installing new air filters in your 500 series larger V8 models produced after 2000. If not done properly you can damage the engine cover and possibly the engine itself.
Please note: Does not include sprocket. The pump has been taken apart and inspected. No excessive tooth scoring. Bolts are loose. The pump will need to be cleaned - oiled and reassembled before installation. Excellent used condition.
These instructions are part of our radiator neck reinforcement kit and a printed copy is included free with the purchase of that kit (see related products below).
Running badly means poor performance. It happens sooner or later to EVERY diesel owner. The word "performance" is often used to describe how well a diesel engine runs once started. The principles discussed will cover all Mercedes diesels from the mid 1950s to the mid 1990s.
A diesel compression test is an extremely important engine diagnostic procedure. It should be done on any diesel you are planning to purchase. More than any other test, it can tell you if you are purchasing a healthy engine.
Changing the V-belts on your older 5 cylinder turbo diesel engine can be a pain. If you have not done it before it can be a REAL pain that leaves you confused and frustrated. In some cases it is possible to damage or break critical adjusting mechanisms if not done properly.
The digital PDF instructions will walk you through the install and detailed photos will visually assist you step by step. PDF is 4 pages long.
If you have a W116 or W126 300SD or a turbo 1981 to 1985 5 cylinder W123 Diesel you must pay attention to your oil cooler hoses. If one of these hoses fail you will destroy the engine unless you are in the habit of looking at your oil pressure gauge every 5 minutes while driving.
In a perfect world your diesel would not leak a drop of fluid. Unfortunately, with the age of your vehicle, it may not be economically possible to eliminate every leak. Sometimes you may just have to live with some leaks.
